Evolution was fueled by endosymbiosis, cellular alliances in which one microbe makes a permanent home inside another. For the ...

Researchers got a better look at chatbots’ thoughts, amateurs learned just how complicated simple systems can be, and codes ...

Exactly 200 years ago, a French engineer introduced an idea that would quantify the universe’s inexorable slide into decay. But entropy, as it’s currently understood, is less a fact about the world ...

To better understand machine learning algorithms, Lenka Zdeborová treats them like physical materials.

The mathematician and author Steven Strogatz and the astrophysicist and author Janna Levin interview leading researchers about the great scientific and mathematical questions of our time.

How do you construct a perfect machine out of imperfect parts? That’s the central challenge for researchers building quantum computers. The trouble is that their elementary building blocks, called ...

Computer scientist Lance Fortnow writes that by embracing the computations that surround us, we can begin to understand and tame our seemingly random world.

While some fret about technology’s social impacts, Raj Reddy still believes in the power of artificial intelligence to improve lives. Before he became a decorated pioneer of artificial intelligence, ...

In the search for the most scalable hardware to use for quantum computers, qubits made of individual atoms are having a breakout moment. Teleporting people through space is still science fiction. But ...

This year, superconductivity — the flow of electric current with zero resistance — was discovered in three distinct materials. Two instances stretch the textbook understanding of the phenomenon. The ...
